Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? No
How many total trend values can be stored? None. Feature available through SF1 or SAGEMAX
What is the controllers role in trending? None. Feature available through SF1 or SAGEMAX
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? No. Feature available through SF1 or SAGEMAX
Programming Method(s) Programmed using menu-driven SOLOPro software or SOLOTool hand held operating device.
Resident vs Non-Resident Program Execution All program execution is designed to be controller resident although the SAGEMAX and/or SF1 can be programmed to perform/supervise unit controller functions. Controller-resident program execution is ensured by selecting the proper controller for the application.
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
Resident Energy Management
Energy management algorithms for this controller can be custom programmed
Pre-programmed/built-in algorithms available, and are fully editable using custom programming
Pre-Programmed/built-in with limited editing via template-based programming
Controller is not typically used for energy management functions
Others See below
Specific Pre-Programmed Algorithms Available
None (custom programming only)
None (not applicable)
Optimal Start/Optimal Stop
Peak Demand Limiting/Load Shedding
Economizer (enthalpy, dry-bulb, CO2, modulating/2-position, etc.)
Additional Energy Management functions are resident at SI
Additional Programming Functions The IX1 can perform linearization, filtering, pulse-counting, demand prediction, averaging, and alarm handling.
DDC Loops (P, PI, PID) No
Automatic PID Tuning Feature No
Automatical-Dial Alarm Support No. Feature available through SF1 or SAGEMAX
Does controller perform multiple retries and buffer/store alarm until connection is made? No. Feature available through SF1 or SAGEMAX
Are multiple destinations possible? No. Feature available through SF1 or SAGEMAX
Upon controller power loss or hardware failure:
Are network communications affected? No
Is loss recognized on/by the network and alarm reported? Yes. Continuous controller diagnostics results in an alarm at the SAGEMAX or SF1 in the event that the control program stops or aborts.
DO and AO response?
Outputs fail to a user pre-specified position
Outputs fail to a normal (unpowered) position
Outputs fail to last position
Other controller has no outputs
Volatile memory functions?
Retained for life of backup battery
Other Upon restoration of power the controller operates at default settings stored in EEPROM that were defined during initial configuration.
Upon restoration of power does the controller:
Auto-reboot without operator intervention? Yes
Automatically reset/synchronize the clock? No
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? No
Upon network or communications failure does controller:
Continue to operate standalone? Yes
Operate with last global settings or user-specified value? N.A.
Do broken network segments continue to communicate within the remaining segment?
(Note: May depend on proper termination of segments for higher speed networks.)
Does network automatically reconfigure upon restoration? Yes
Does network store 'loss of communications' alarm with time of event? Yes
Additional Information (optional)
Self Test Diagnostics
Does controller have internal self-test diagnostics to check:
Processor failure? Yes
Internal hardware failure? Yes
Open/shortened sensor? Yes
